Detection of signals in MC-CDMA using a novel iterative block decision feedback equalizer
(IEEE, 2022)
Artículo / Artikulua,
This paper presents a technique to mitigate multiple access interference (MAI) in multicarrier code division multiple access (MC-CDMA) wireless communications systems. Although under normal circumstances the MC-CDMA system ...
Study on isolation improvement between closely-packed patch antenna arrays based on fractal metamaterial electromagnetic bandgap structures
(Institution of Engineering and Technology, 2018)
info:eu-repo/semantics/article,
A decoupling metamaterial (MTM) configuration based on fractal electromagnetic-bandgap (EMBG) structure is shown to significantly enhance isolation between transmitting and receiving antenna elements in a closely-packed ...
Impedance bandwidth improvement of a planar antenna based on metamaterial-inspired T-matching network
(Institute of Electrical and Electronics Engineers Inc., 2021)
Artículo / Artikulua,
In this paper a metamaterial-inspired T-matching network is directly imbedded inside the feedline of a microstrip antenna to realize optimum power transfer between the front-end of an RF Wireless transceiver and the antenna. ...
Optimum power transfer in RF front end systems using adaptive impedance matching technique
(Nature Research, 2021)
Artículo / Artikulua,
Matching the antenna’s impedance to the RF-front-end of a wireless communications system is challenging as the impedance varies with its surround environment. Autonomously matching the antenna to the RF-front-end is therefore ...
Dual-polarized highly folded bowtie antenna with slotted self-grounded structure for sub-6 GHz 5G applications
